This low voltage room thermostat opens on temperature
rise and is designed for use on various types of heating
equipment. It is equipped with a heat anticipator which
may be adjusted for primary control current draws of .15
to 1.0 Amps.
SELECTION LOCATION
The proper location of the room thermostat is most
important to insure that it will provide a comfortable
ambient temperature. Observe the following general
rules when selecting a location:
1. Locate it about 5 ft. above the floor.
2. Install it on a partitioning wall, not on an outside, win-
dows, or adjoining outside walls.
3. Never expose it to direct light from lamps, sun, fire
places, etc.
4. Avoid locations close to doors that lead to outside,
windows, or adjoining outside walls.
5. Avoid locations close to radiators, warm air registers, or
in the direct path of heat from them.
6. Make sure there are no pipes or duct work in that part of
the wall chosen for the thermostat location.
7. Never locate it in a room that is warmer or cooler than the
rest of the home, such as kitchen or hallway.
8. The living or dining room is normally a good location,
provided there is no cooking range or refrigerator on
opposite side of wall.
ROUTING WIRES TO LOCATION
1. Before drilling hole in wall at selected location, take up
quarter round and drill a small guide hole for sighting.
From basement, drill 3/4" hole in partition floor next to
guide hole. (On basementless houses, drill 1/2" hole
through ceiling above partition.)
2. Probe for obstructions in the partition. Then drill 1/2"
hole through wall at selected location.
3. Through this hole in wall drop a light chain, or 6" chain
attached to a strong cord, and snag cord with hooked
wire from basement. (On basementless houses, drop
cord from ceiling and snag it at the thermostat location.)
4. Attach thermostat cable to cord and pull cable through
hole in wall so that 6" of cable protrudes.
MOUNTING THERMOSTAT
1. Pull thermostat wires through large hole in center of wall
mounting plate and fasten wires beneath two terminal
screws on bottom side of plate.
2. Push excess wire into wall or switch box and plug up hole
to prevent drafts from affecting thermostat operation.
3. Thermostat must be level to assure optimum performance.
Place level on top of wall mounting plate and mark hole
locations for mounting screws provided. Again place
level on top of plate to be sure it is level. Then tighten
screws.
4. Remove cover from thermostat base by pulling outward.
Remove and discard pad (shipping protection for switch).
Place thermostat base onto wall mounting plate and
tighten all three screws securely. Then snap on
thermostat cover.
WIRING
All wiring should be done according to local
and national electrical codes and ordinances.
WIRING AS ROOM THERMOSTAT
Because of the many possible uses of these room ther-
mostats, no wiring diagrams are presented. Use the wiring
diagram that is shown on the instruction sheet that is packed
with the primary control, or the one that is supplied by the
manufacturer of the heating equipment.
